Idaho Residential Rates

This rate design divides a customer’s monthly energy usage into separate tiers based on how many kilowatt-hours of energy a customer uses. The customer is charged an increasingly higher rate for energy used in each additional tier.

With our tiered rate design, customers are encouraged to conserve and be energy efficient. The less energy a customer uses, the lower the amount of energy charged at a higher rate. By staying in a lower tier, customers pay less.

The tiered rate design helps customers identify opportunities to manage their personal energy usage and monthly bill. Learn more about your bill in this diagram and bill glossary.

By being energy efficient, we all have the power to control our costs.

As an example, a residential customer who uses 1,050 kilowatt-hours (kWh) during the month of March would be billed at the non-summer rate. The breakdown of this customer’s energy charges according to the tiered rate structure would be:

800 kWh x 8.0746 cents (tier 1)

$64.60

+

250 kWh x 8.9020 cents (tier 2)

$22.26

1,050 kWh

=

$86.86

If the same customer used 2,225 kWh during the same time period, the energy charge would span all three tiers:

800 kWh x 8.0746cents (tier 1)

$64.60

1,200 kWh x 8.9020 cents (tier 2)

$106.82

+

225 kWh x 9.8588 cents (tier 3)

$22.18

2,225 kWh

=

$193.60

Alternately, if that same customer used only 800 kWh during the same time period, the energy charge would fall into the lower-price tier 1, for a total of:

800 kWh x 8.0746cents (tier 1) = $64.60

Being energy efficient saves customers money!
